I I'Thus, a positiveandcbracing connectionis es- :tablished' betweenithefmain "derrick legs and I the reenforcing derrick legs through the improved brackets, "Furthermore, by reason of the relative right angular disposition of the outer faces offthe web like extensions 6, it

I? ,f v so Duetothepeculiar formation and arrangement otthe'curved leg engaging 'arms 8, it

I will be seen, especially uponreference-to the Figure 3, that those portions of the reenforcing-le'gs received between the paired arms willbe 'positionedadjacent the pivotal conf nection between'the' plates land 2 afforded *by1theihooked fingers 12 engaging portions s j- [o'fthe pintle c ar'ried by the bearing fingers 18am 14. j v I Y '10 between the arms 8 will, with theclamp- 5 ing connection of-the U-shaped bolts 18, im-

part lateral and opposed stresses to the sub- 1 stantially complemental bracket plates 1 and a Th2 and therefore, it 'will be'understood that undesirable or accidental {disengagement of 'Such engagement of the reenforcing legs thehooked fingers 1'2 withithe bearing pintle I means;

To satisfy thisfldesire, the reen- -forcinglegs 10 may be now'readily removed v or disconnected bydisengaging the locking l of the U-shaped clamping bolts '18 and with-f drawing said clamping V v, ings 7 in the web-like extensions 6. At this time, the 'derrick'reen'forcinglegsor thesecj tions of which they arecomposed maybe nuts 19 from the screw'threaded extremities 'hand, bolts from theopen- I easily removed from between the seats afing derrick, standing upon the operation and also, leaving intact, the bracing connections forded them through the curved and paired I engaging arms 8, thus leaving a lightpumpf 20 and 21 with the substantially right angularly opposed extensions 6. I

Manifestly, the construction shown is ca pable of considerable modification and such modification as is within the scope of my outer faces of the web-like a cla1ms,.I consider within the spirit of my I invention.

I claim:

1. A derrick leg relatively angularly bracket comprising a leg receiving 7 body portion, arranged plates integralwith and disposed longitudinally of said body portion, and re- I legreceiving means integral with the body portion and the opposite ends of said plates, said receiving meansbeing arranged between the plates and in longitudinally opposed relation.

'2 A derrick leg bracket comprising a leg receiving bodyportion, relatively angularly disposed plates integral with and disposed longitudinally of said body portion, and releg receiving arms integral withthe body portion and theopposite ends of said plates,

certain of the sides of saidreleg receiving arms being formed with cradle like portions whereby to receive a releg therein.

3. A derrick legbracket comprising a tn bular leg receiving body portion, relatively 8 right angularly arranged platesintegral with j and disposed longitudinally of said body portion, and releg receiving arms disposed trans versely ofjand integral with said body portion and with the opposite ends of said plates,

certain of the sides of said arms being formed with cradle like receiving portions disposed between said plates in longitudinally opposed I relation.

tachably and pivotally connectingone side of said plates together, means for detachably connecting the opposite sides of said plates, I

a substantially right 'angularly' disposed brace and girth receiving web like extension I formed with each plate in proximity to said ing the plates, opposed derrick releg engaglng arms formed on the extremities of said right angularly disposed web extensions and clamping means connected" to said arms In witness whereof I have hereuntoset my "CARL H. BESSE.

rmeans for detachablyand pivotally connecti whereby the derrick relegs maybe detachably connected to said arms.
